$93 I 3Z\ 6 31! III/I u B .B'SLOCOMBE M'FULTON mvsMToas Patented Jan.10, 1950 UNITED STATES: PATENT OFFICE This invention relates to textileapparatus andparticularly to warp beams, and is especially concernedwith warp beams provided with endflanges which are adjustable along thelength oithe beam barrel so to varythe length of barrelon whichtheyarnis wound.

In one form of warp beam with adjustable flanges the barrel isiormed'with a screw thread extendin from the ends of the barrel towardsthe middle, and the flanges are mounted on bosses which are internallythreadedso that'theycan be screwed along the length of the barrel toadjust the position of the flanges along the barreli Locking collars areprovided on the barrel outside the'flanges, which are screwed up tightlyagainst: the bosses when the'flangesare in the desiredposition so astoprevent accidental rotation of the flanges. This form of beam is verysatisfactory in many respects but-is'open to' the disad vantage that thescrew threads on the barrel of the beam are liable to bedamaged,particularly in the transport, handling and storage of the empty beams,when the flange of one beam is apt to strike against the barrel ofanother and to damage the unprotectedscrew threads thereof.

It is an object of 'the'present invention to provide a warp beam withadjustable flanges in whichthis disadvantage is overcome or verysubstantially reduced.

According to the present invention the flange of a warp beam is carriedon the inner end of a long collar that fits over the end of the beambarrel, the beam barrel and part of" the bore of the collarbeingscrew-threaded for the attachment and adjustment of the" collar andflange,

while apart (generally less than one half) of'the length of theboreadjacent'to the inner end of the-collar isleft plain. The plain partof the bore of the collar then-covers, in the outermost position of theflange, the screw threadsof the barrel that are engaged by the threadsof the collar'in the innermost :position of the flange, and the threadsonthe barrelare thereby protected against'damage. It is desirable'toprovide locking means for preventing accidental rotationof theflange andcollar on the barrel, and consequent disturbance of the adjustment oftheflange position By the arrangement described above; anad justment of theflange equal in length tothe plain part oi the bore is availabie'withoutany exposure of the screw threads; The assembly may, however, bearranged to" give a somewhat greater adjustmentsince" it is permissiblefor a limited length of the-threaded part of the barrel 65 V tobeexposedinsidetheiiange; Thread's exposed immediately insidetlie'flange are not likely to-be damagedby theflanges'of other beams; sincethe parts of the flange assembly lying outside the inner face of theflange, e. gisupporting;buttresses on the outside" of the flange-and thecollar itself which carries the flange; preventthe edges of the flangefrom" coming into contact with the barrel of another" beam-close to theflange'thereof.

While the range of adjustment afforded by the invention is limitedthisis not a serious disad vantage since it iseasy'flbyproviding a smallnumber of'bariel's (ii-"different lengths to anew for" a wide range ofdistances between flanges; Moreover it would in" any case be hi'ghlyincon venient either to" have a long overhang of idle barrel with noyarn thereon extending beyond the-side-frames of the loom; or'for'thesake of accommodating a longbarrel, tduse a wide'loom for weaving: arelatively narrow fabric; The complete beam in accordance with thepresent invention; withit's flange assembly at each end, is lightin'st-i'ucture andis; moreover, particularly well adapted to beconstructed wholly or to a large extentof'lightalloyl The adjustment ofdistances between flanges is quick and easy to' make and theflangesoidifferent diameters may be readily: exchanged for one? another.

While the collarand the? flange may be made in one piece, it i'sfmoreconvenient" in manufacture to make them astwopieces; a collar that is'internally screw-threaded over'the" whole or the greater" part of itslength, and a bossed flange" having a bore which ispartly plain andadapted tefi't closely/round the'barrel of the'beam and partly enlargedand screw-threaded in order to" bescrewedf tightly over" one=end oi the"collar,

the 1 latter being provided with" external threads for this purpose. Iheplain part of the bore' of" tiie'fiangeandc'ollar assembly a'sawhole isthus provided; whollyor in p'ar't; by the'bore of the flange'boss. I

Theouter' surfaceof' the collar may conven- 4 iently be'fonnegi as 'aohaing'race or 'ruiile adapted to be engaged by'chains or ropes forcontrolling the beam let-oi! in'tlie usuarway'. The end of the collarmay be closed (since the. end of the barrel'does not extend through it)and'arrange'd to receivea screwed pike or trunnionfor convenience in thetransport and handling: of the beam. For'the" purpose of mounting thebeam in the'loom a suitable" bearing'surface maybe provided onthecollar" outside the chaingrace' orruflie;

A convenient form of lockingmjeans' to pre-- ing torque during weavingshould tend to drive the flanges inwards along the length of the 4 Theflange member 1 comprises a boss IS, the bore of which (including theflange thickness) is about 3 long and fits closely over the barrel I for2" of its length at I1. The remaining part I8 of the bore, 1 in length,is enlarged and screw threaded so as to be screwed tightly over theexternal threaded part II) of the collar 6. Four radial holes I9 arebored, threaded and countersunk through the boss I6 to correspond withthe four holes I2 of the collar 6. The holes I9, I2 receive four lockingscrews 20 with counter-- sunk heads, the ends of which are adapted tobeam,'against the'pressure of the yarn wound on the beam. In this waythe strain 'on the locking means is partly balanced and, moreover, thereis little tendency for the warp threads to be trapped against theflanges.

The barrel of the beam preferably consists engage with the flats 5milled on the surface of thebeam barrel I. The screws 2% thus serve thedouble function of preventing the flange member I from turning on thecollar 6, and the collar 6 from turning on the barrel I.

The flange "2I itself is in thickness and is provided with of a tube oflight metal of, say, quarter-inch gauge, provided at intervals withslots to receive the tying-on knots of the warp. .The barrel may,however, be made of woodwith a screw-threaded metal sleeve fittedovereach endto receive the flange assembly. The flange and collar maylikewise be made of light alloy. Where, however, chains or metalbrake-shoes are .to be used for controlling the beam let-off, it ispreferable to make the collar either of cast malleable iron or of alight alloy on'which'a surface skin, of hard metal, such as ,chromium isdeposited by spraying or by electro-chemical methods.

By way of example two forms of warp beam according to theinvention. willnow be described in greaterdetail with referenceto the accompanyingdrawings in which- Figurel is'an elevation of one form of beam in whichthe right-hand end is shown in external view and the left-hand end insection, with its parts separated. Q.

.Figure 2 is an outside face view of the beam flange of a second form-ofbeam, and V Figure 3 is a section through a flange assemblyincorporating thefflange shown in Figure 2.

Referring to Figure l, the beam comprises a barrel I in the form of'alight metaLtubefi" in diameter and A? '*in thickness slotted every 6f asat 2 to receive thetying-on knots of the warp. The barrel I is screwthreaded at'both ends 3, 4 for a distance of 5%f', the threads at 3being right-hand threadswhile the threads at 4 are left-hand threads.Into thescrew threads at the ends3, 4 are milled four flats 5 wide and 3long,.parallel to the axis of the barrel I and extending to within'z hof the ends thereof.

-On each end of the barrel I is screwed a flange assembly consistingprincipally'of 'a. collar portion 6 and a flange portion 1. Thecollar 6is 6" inoverall length and; its'outer surface is formed so as toconstitutea bearing surface 8 1" wide for the mounting of the beam in aloom, a chaingrace or brake surface 9 2 'fwide and a threaded part I 1wide; Four holes I2 are bored radially through the threaded part ID at.a distance of A" from the inner edge thereof. The bore of the collar .6is screw threaded over the whole of its length'to match thescrew threadon the corresponding end of the beam barrel, I and is closed at theouter end of the collar by means of a disc I3 welded or otherwisesecured to the collar. The disc [3 is centrallybored and threaded forthe reception of a pike or. trunnion I4, which issecuredby means of alock nut I disposed on the inner face of the disc I 3, and facilitatesthe handling of the beam and its lo-- cation during beaming. a

eight radial buttresses 22 extending from the edge of the flange 2I tothe boss It, the buttresses being 1 in width'and l in depth at the boss2 and 3 is adapted to be fitted to a beam barrel of the kind describedwith reference to Figure l and is somewhat lighter in construction thanthe assembly shown in Figure 1. It comprises, like that of Figure l, aflange member 25 and a collar 'member 26. The flange 28 ofthe flangemember is only in thicknessbut is reinforced notonly by eight buttresses29 but also by a finger ring 30 1" in depth and '7-;; in radius and by afurther ring 3I about thick and deep at the separated by two flanges 36bevelled to 45 and.

A2" in maximum width and thickness. Four holes 31 are bored at equalintervals round the threaded portion 35 to correspond with four holes 38bored through thethickness of the boss 32 for the reception oflockingscrews 39. tachable pike 49, secured by means of a locking nut 4| in theend plate 42 of the collar 26, is also provided. j V

Each ofthe beams described above has a flange adjustment of 3" at eachend, the adjustment being capable of being made in steps each equal toA; of the pitch of the-screw threads on the barrel I. The screw threadsare completely concealed for the first two inches of the adjustment andonly one inch of thread is exposed when the flanges are in theirextremeoutward position, the threads so exposed being nevertheless protectedfrom damage by the. proximity of the flange. By the provision of fourinterchangeable barrels I of 48", 54", 60" and 66" length re spectivelyany width of warp from 36 to 60" can be accommodated.
